Self Report
The International Outcomes Inventory for Hearing Aids (IOI-HA) was developed as a result of a meeting in Elsinore sponsored by the Oticon Foundation. The aim was to devise a short set of items that would capture key aspects of the known important dimensions of hearing aid use, hearing aid performance, satisfaction, residual disability and handicap and overall quality of life. There have been several studies using the IOI-HA in various clinical settings, and the scale has been translated into many languages. Most of the initial group involved in the scale’s development are ICRA Fellows, and ICRA has taken on the role of “clearing house” for project ideas, potential collaborations, new translations, and data-base identifier.
The IOI-HA covers a minimal set of seven core outcome items which are sufficiently general to apply to many different types of investigations carried out in different countries in the world. The items are practically oriented and comprise a mini-profile more than a scale. It was developed at an international workshop on “Measuring Outcomes in Audiological Rehabilitation Using Hearing Aids” in Eriksholm in Denmark. The IOI-HA was not intended to replace existing outcome measures but to serve as a useful addendum to existing measures in a research context. It might potentially function as a stand alone tool for quality assessment.

Inventory of IOI-HA
The following documents consist of 3 pages. The first two pages are an article (in English) entitled “Translations of the International Outcome Inventory for Hearing Aids (IOI-HA)”. The third page is the actual questionnaire in the specified language.
Tips:For scoring purposes, responses from left to right on the page are assigned a value from 1 to 5. The values are then added. Higher scores indicate a more favorable outcome.
